We want to import data on a Linux system. So we have 2 Java files for the
import. One (*OrientDBMain.java*) is for creating an object that is doing
all the work. The other (*OrientDB.java*) contains all the database
functions like setting an index and so on. The second files starts with:
public class OrientDB {
private OrientGraphFactory factoryGraph;
private ODatabaseDocumentTx db;
private String csvPath;
@SuppressWarnings("resource")
public OrientDB(String dbPath) {
OGlobalConfiguration.STORAGE_KEEP_OPEN.setValue(true);
OGlobalConfiguration.ENVIRONMENT_CONCURRENT.setValue(false);
db = new ODatabaseDocumentTx(dbPath).create();
}
...
Running this in Eclipse on a Windows and MAC works well. No error and data
is correctly imported.
But now we wanted to run this on our Linux system. So we setup a Maven
project (m2e) and exported a Jar file with all the dependencies here:
<project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi=

But if we run that Jar now we are getting some errors. They say that there
is some OCommandExecutorNotFoundException thrown. But how can that be if it
run great directly in Eclipse? We have 2 args {pathtoimportdata,
pathtodestinationdb}.

So the question is right now. Why does it throw that error and why does it
work properly in Eclipse. And maybe do you know other way to compile import
scripts for OrientDB in an easy way with less effort.
Thank you.
